Understanding the principals of living microbes and identifying my unknown bacteria through numerous biochemical and metabolism tests‚ with the outmost confidence‚ Proteus vulgaris had the precise qualifications. The point of this report is to further explore the identification of my unknown bacteria by revealing the results of the experiments and comparing them to the other six known bacteria: Micrococcus luteus‚ Staphylococcus aureus‚ Staphylococcus epidermidis‚ Alcaligenes faecalis‚ Escherichia coli‚ and

What Is Microbiology? Microbiology is the study (logy) of very small (micro) living (bio) things. Microbiology is the study of microorganisms. These "bugs" include: bacteria (that’s the Latin plural for bacterium); viruses (that’s the non-Latin plural for virus - virii sounds weird‚ so I don’t say it); and‚ fungi (that’s the Latin plural for fungus - which by now you have guessed‚ or already knew‚ and may not be all that interested to know‚ anyway). Microbiology is actually made up of several

There are several types of staining through which the bacteria can be identified based on the color and shape. The staining methods used in the lab are Gram Staining‚ Capsule Staining‚ Endospore Staining‚ and Acid Fast staining. One of the most significant method of

Theodor Wilhelm Engelmann was a German microbiologist whose 1882 experiment measured the effects of different colors of light on photosynthetic activity and showed that the conversion of light energy to chemical energy took place in the chloroplast. In 1881‚ he observed the movement of bacteria towards the chloroplasts in a strand of “Spirogyra” algae. Engelmann hypothesized that the bacteria were moving in response to oxygen generated by the photo synthetically active chloroplasts in the algae.
